Strategies for data acquisition and processing will be discussed in the context of the Facility for Rare Isotope Beams (FRIB). Design decisions include selecting and designing electronics hardware, data acquisition cards, firmware design, and how to integrate with EPICS control system. With over 300 diagnostic devices and 16 unique types of devices, timing for synchronous data acquisition is important. Strategies to accelerate development as well as reduce maintenance requirements will be dis-cussed, including using common hardware and firmware whenever possible, and defining a common data report-ing structure for use by most devices. MicroTCA.4 plat-form is used to integrate data acquisition cards, distribute timing information, and machine protection signals.

The Los Alamos Neutron Science Center (LANSCE) is currently upgrading the beam diagnostics capability for the Isotope Production Facility (IPF) as part of an Accelerator Improvement Project (AIP). Improvements to measurements of: beam profile, beam energy, beam current and collimator charge are under development. Upgrades include high density harps, emittance slits, wire-scanners, multi-segment adjustable collimator, data acquisition electronics and motion control electronics. These devices will be installed and commissioned for the 2017 run cycle. Details of the hardware design and system development are presented.

The Los Alamos Neutron Science Center (LANSCE) is currently upgrading equipment that is used to digitize transverse beam profile measurements. Emittance measurements were originally digitized using legacy equipment, known as RICE (Remote Indication and Control Equipment). This required 38 RICE modules distributed along the half-mile long accelerator simultaneously recording 4 channels each to populate the 76 data points needed to create a single emittance profile. The system now uses a National Instruments cRIO controller to digitize the entire profile in a single chassis. Details of the hardware selection and performance of the system for different timing structures are presented.

In High Energy Physics (HEP) experiments, devices are required to withstand high radiation levels. As a result, detectors and electronics sitting in the inner detector layers must be irradiated to determine their radiation tolerance. To perform these irradiations, CERN built during LS1 a new irradiation facility in the East Area at the Proton Synchrotron (PS) accelerator. At this facility, named IRRAD, a high-intensity 24 GeV/c proton beam is used. During beam steering and irradiation, the intensity and the transverse profile of the proton beam are monitored online. The IRRAD Beam Profile Monitor (BPM) uses a set of four 39-channel pixel detectors constructed using thin foil copper pads positioned on a flex circuit. When protons pass through the copper pads, they induce a measurable current. To measure this current a new data acquisition system was designed as well as a new database and on-line display system. In this work, we present the design and the architecture of the IRRAD BPM system, some results on its performance with the proton beam, as well as its planned upgrades, including its utilization for monitoring irradiations with an intense 300MeV/c positive pion beam at PSI.
